Finally using Vibroplex Paddle

I decided to sign up for the CWops CW Academy.  They have small, instructor led classes that meet for an hour twice a week, for eight weeks.  In addition, there is an expectation of an hour of practice sending/receiving each day, so it is pretty intense, but a lot of fun. My instructor, Joe KK5NA, makes it enjoyable and fresh.

With all that CW practice, I have radios and keyers all over the house now (bedroom, den, and of course shack).  I’ve started to run out of paddles.  I broke into a box that I received 7 years ago – A 100th Anniversary ARRL Commemorative Vibroplex paddle to hook up to my Flex-6600M.

Keeping your paddle in place

I’ve always been rather ham-fisted when it comes to sending Morse Code.  Not so much that I squeeze the paddles so much they bend, but rather I knock the paddle all over the table.  It’s hard to send a “5” when the paddle is moving!  Some of that is age and some of it is lack of practice.  After acquiring a UR5CDX CT73 MB-L, “travel” paddle, the problem was amplified due to its light weight.

A friend of mine, Bruce NJ3K, had discovered DXengineering’s “Paddle Pad” and suggested I try one out.  They come in two sizes (the photo below is the larger size).  Both the bottom and top of the pad is sort of sticky (but not in a messy way).  Sure enough, when I put the paddle on the pad, it no longer moves.  Thank you Bruce!

The company that makes the sticky pad for DXengineering is HandStands, which sells through Amazon and other dealers for about the same price (without the pretty DXengineering logo of course).

Three more RI parks activated

This past Tuesday, my wife and I (and our lab Jaclyn) headed out to the three RI parks furthest from our house: Simmons Mill, Sapowet Marsh, and Haines State Park.  It was about an hour to the furthest one, and we were back home about six hours later.  One station, WB4KTU, Loyce in Alabama, managed to work me in all three parks.  Another hat-trick!

With 36 parks completed, I’m in position 45 (Top 5%) for 2021, and in the top 7% since the program began.

Light Travel Paddle from Ukraine

From time to time, some beautiful work or art, that is also a Morse key, catches my fancy.  I recently purchased a small dual-lever paddle from UR5CDX, for about $150 including shipping (surprisingly fast too — about a week via international post).

At home I go big and heavy to deal with my ham-fist which knocks keys all about the desktop.  But when traveling (like POTA), size/weight becomes an issue.  I haven’t used this key on the road yet, but I fully expect I’m going to have to hold it with one hand while sending as I do other small keys.  That said, it’s almost too pretty to use.

POTA Gold Activator

After completing 30 unique park activations yesterday, my “Gold Activator” certificate arrived today:

I continue to gather metrics on activations.  I noted in doing three activations yesterday that my old Toughbook CF-30 laptop had used 30% of it’s battery capacity, indicating I could have done 6 to 8 parks on a single charge.  In addition all three activations took 5.7 AH from my LiFePO4 battery.  The QSO rate was close to one a minute in all three parks, and I was on the air for about 30 minutes at each park.  While doing three parks in a row was fun, I’m fairly certain that doing four would have lowered the “fun” factor significantly.  In the future I’ll try to do 2 or 3 activations in a day.

The POTA group keeps track of Activation and Hunting activities with a Leaderboard.  You can look at it two ways, either by year, or overall.  I noted that I am in the top 10% of activators both overall and for 2021.  That just says it is fairly easy to make a significant impact even though there are thousands of people participating (9,586 as of today, making 2.3 million contacts)

POTA Hat Trick

Today was a glorious weather day here in Rhode Island, so my wife and our yellow lab piled into the van and headed out for three park activations (Lynn and Jaclyn walk the park trails while I jabber on the air).  We wound up at East Beach State Park (K-7865), then Kimball Wildlife Management Area (K-7518), and finished the day at Burlingame State Park (K-2871).

All three activations went swimmingly with 20 or more contacts completed in about 20-30 minutes.  The parks were only a few miles from each other.

Amazingly enough, three people managed to work me in all three parks, earning themselves a RI-POTA Hat Trick:

    • Neil K7SEN
    • Tom W8NWG
    • Dave N9VFR

I am indebted to everyone who works me during an activation, continuously reaffirming that Amateur Radio is a wonderful hobby.  Being able to get outside these past few months has saved my sanity.  So thanks to Jason W3AAX and all the POTA administrators, and especially the regional coordinators (a shout-out to my 4-area regional coordinator, Bill Deloach, K4WP, who has processed all of my 30 logs).

QRP Labs QCX-mini

I need another radio like a submarine needs a screen door.  That said, I couldn’t resist buying a QCX-mini from QRP Labs.  This is a $55 partial kit (all SMT devices already on the board), with a $20 case, making a $75 single-band 5 Watt CW Transceiver.  It was under $100 including express shipping from the UK.

I’ll keep track of assembly time and any issues I run across.  BTW, the photo doesn’t give you an idea of the size.  It will fit in the palm of your hand easily and is about 1/2″ thick.

More POTA Swag

I just completed hunting 200 unique parks:

And I received a Winter Hunter Award for 2021 (for working someone in the first week of the new year):

Silver POTA Activator

I have continued with Parks On The Air this winter.  It’s been a bit of a challenge due to weather, but pretty much every week there has been one day, sandwiched between snow or ice storms, that I have been able to get outside.  At this point I have activated 20 of the 52 parks in Rhode Island.

A charger for LiFePO4 batteries

In an earlier post, I described a rather inexpensive 16 AH LiFePO4 battery.  I’ve used that for my last three activations, and so far it works as expected.  A few folks have asked me “What charger do I use?”.  I decided to go with a 4 Amp LiFePO4 charger like this one from HamRadio.com (the charger used for BioEnno batteries):  https://www.hamradio.com/detail.cfm?pid=H0-014845

Similar chargers are also available on eBay

LiFePO4 batteries are VERY efficient, like 98-99% efficient.  In other words, if you take 10 AH of capacity away from it, you are going to put almost exactly the same amount of power back into it.  In other words, a 16 AH battery, fully discharged, will take 4 hours to fully recharge using a 4 Amp charger.

Please note that the Battery Management System (BMS) installed in a multi-cell packs has cell balancing circuitry built-in.  It tries to make sure that the series connected batteries never get into a condition where the voltage on one cell differs from the voltage on another cell.  Because of the BMS, it is often necessary to keep the battery connected for a few hours after the charger indicates full charge.
